Product informations
EK220, the battery-powered electronic volume converter with flexible data logger function and configurable serial interface; this device detects low-frequency pulses of the measured gas volume under operating conditions from a gas meter, measures the operating pressure and temperature of the gas, calculates the compressibility coefficient K and the conversion factor C. Using these data it is possible to calculate the gas volumes at standard conditions, the flow rate values at standard conditions and the flow rate values at operating conditions.
Product features
- consisting of a central unit equipped with an integrated or external pressure sensor and a temperature sensor
- the sensors are permanently connected to the unit
- the compressibility coefficient K can be programmed as a fixed value for all gases
- used for various applications in the field of natural gas measurement and station monitoring
- high accuracy
- four sealable and freely programmable digital outputs
- optical interface for parameterization and reading (IEC 62056-21)
Applications
- conversion of gas volumes for billing purposes
- data storage (data logging) for various applications
- assembly of measured values and typical functions of a measuring station
